Masked Ramen

even as Craig he looks  quietly uncomfortable with touch.

He doesn't get super mad or anything but he dose move away from boss guy even puling his arm away, not in an attempt to get into the mail room but just to create space between them (Craig seemingly has a really great attitude about being positive and never gets mad or really upset).

you can see a little more of suction cup man not liking touch in "business or pleasure" where he is furious and yelling at the movers but actively gets out of their way.

Im not suggesting he cant stand any touch at all ever, i think rather that he hates unwanted or unexpected  touch, that's why as Craig he was fine with hugging business guy because he had a say in it (he had the option to just not get up from his chair or to bull away from the hug).
